FeynAmpDenominatorSimplify[exp] tries to simplify each PropagatorDenominator in a canonical way. FeynAmpDenominatorSimplify[exp, q1] simplifies all FeynAmpDenominator's in exp in a canonical way, including some translation of momenta. FeynAmpDenominatorSimplify[exp, q1, q2] additionally removes integrals with no mass scale.
FDS can be used as an alias.
